[HLSL][LongVec] Add support for the clip intrinsic

Right now we are going to XFAIL the tests for Clang in offload
> XFAIL: OffloadTest-clang-warp-d3d12 :: Feature/HLSLLib/clip.long-vector.32.test (146 of 710)

Even though we enabled clip to accept long vectors in this pr: https://github.com/llvm/llvm-project/pull/216905/changes#diff-2607df2f2d2dab495e03c84232309bad5e0cfe5cec821548a921d7232cba185bR45

It is likely failing because of the any intrinsic.
